RIM, Qualcomm, Intel, HP, Huawei, Sony, Nokia, Philips and Cisco also have representatives at the summit, which is being overseen by the UN's International Telecommunications Unit (ITU).

According to the ITU, the meeting aims to "provide a neutral venue for industry, standards bodies and regulators to exchange innovative ideas that can guide future discussions on whether current patent policies and existing industry practices adequately respond to the needs of the various stakeholders".

ITU secretary general Hamadoun Toure said: "We are seeing an unwelcome trend in today's marketplace to use standard-essential patents to block markets."
